Abstract
A storage proxy receives different abstracted memory access requests that are abstracted from the original memory access requests from different sources. The storage proxy reconstructs the characteristics of the original memory access requests from the abstracted memory access requests and makes prefetch decisions based on the reconstructed characteristics. An inflight table is configured to identify contiguous address ranges formed by an accumulation of sub-address ranges used by different abstracted memory access requests. An operation table is configured to identify the number of times the contiguous address ranges are formed by the memory access operations. A processor is then configured to prefetch the contiguous address ranges for certain corresponding read requests.
